Earthquakes in numbers

Earthquakes occur along moving cracks on the ground called faults. The largest cracks are called tectonic plate boundaries.

One of tectonic plate boundaries is the famous Pacific Ring of Fire. For example, between 1965 and 2016, the Philippines, a country along the Pacific Ring of Fire, experienced 5 to 43 earthquakes annually, considering only those with at least magnitude of 5.5.

It is estimated that a magnitude 9.0 earthquake is equal to 12,600 Hiroshima bombs.

Some of the biggest earthquakes in the last 5 decades occurred in the Philippines, Japan, Indonesia, and China.

The areas with most number of deaths occurred in densely populated areas. Around 50 percent of the total number of casualties from 1965 to 2016 came from only three countries: China, Indonesia, and Haiti.

Historically, there were a lot of low-magnitude earthquakes and very few high-magnitude earthquakes. But when these rare, high energy earthquakes hit dense cities, they are devastating.

In the Philippines, a fault passing through Metro Manila is said to be ripe for a big earthquake. This earthquake is popularly referred to as "The Big One." It is projected that this earthquake will create a massive devastation to human lives and property.

The "Big One" is coming but we don't know when. However, we can prepare ourselves in case the event happens. Here are some tips on what to do before, during, and after an earthquake.

It is best to build your emergency kit that contains necessities such as food, water, medicine, gloves, and important family documents. Also, include an emergency plan in your emergency kit. Emergency plan provides maps, routes, and contact information. It is best to coordinate with your baranggay regarding your emergency plan.

Do not panic. Get your emergency kit and follow your emergency plan. Get updates from media and follow public announcements.

Stay away from telephone wires, eletrical posts, and broken glass to prevent any possible injuries. If possible, remain updated with public announcements and stay calm. Use your emergency plan to keep in touch government.
